[ADO-ODBC] WatermarkingAlgorithmResearchandImplementationBas DL : 0: In this paper the watermarking programs based on the discrete cosine transform (DCT) domain DC component (DC) is adopted. Through adjusting the block DCT coefficient of the image the watermarks are hidden. And blocking the selected image according to 8×8 pixel, then dividing the selected image into four non-overlapped sub image blocks according to 4×4 pixel, and thus the watermarks are embedded through adjusting their DCT coefficient. The experimental results show that the method has strong robust.
